随着国民经济的发展,放射性同位素的应用日趋广泛,特别是放射性同位素仪表的应用增长较快。有些使用单位有关放射源的资料残缺不全,使放射卫生防护监督部门无法按章实行监督。为了保护使用人员的安全和发放放射卫生许可证,我们利用现有的仪器,以半减弱厚度法和照射量率反推法,对其放射性核素的种类及其活度进行了测试、鉴定。
With the development of the national economy, the application of radioisotopes is becoming more and more widespread, especially the application of radioisotope meters has been growing rapidly. The incompleteness of the information on some radioactive sources by some users makes it impossible for the radiation health protection supervision department to exercise supervision in accordance with the regulations. In order to protect the safety of users and issue radiological sanitation licenses, we used existing instruments to test and identify the types and activities of radionuclides by using the semi-attenuated thickness method and the inverse dose rate method.
